SHOWCASE ZINC MINE OF THE WEEK - MCARTHUR RIVER

The McArthur River mine is one of the world's largest zinc, lead and silver mines, situated about 70 kilometres southwest of Borroloola, near the Gulf of Carpentaria in the northeastern Northern Territory, Australia. It is operated by McArthur River Mining (MRM), a subsidiary of the Swiss mining company Glencore. Although discovered in the 1950s, when it was originally called the HYC or "Here's Your Chance" deposit, it only opened as a mine in 1995. Initially an underground mining operation, the mine has been converted to open-cut - "Mining.com", Wikipedia.

MINING ROCKSTAR OF THE WEEK - FLUORITE!!

Fluorite is an important industrial mineral composed of calcium and fluorine (CaF2). It is used in a wide variety of chemical, metallurgical, and ceramic processes. Specimens with exceptional diaphaneity and colour are cut into gems or used to make ornamental objects. Fluorite is deposited in veins by hydrothermal processes. In these rocks it often occurs as a gangue mineral associated with metallic ores. Fluorite is also found in the fractures and cavities of some limestones and dolomites. It is a very common rock-forming mineral found in many parts of the world. In the mining industry, fluorite is often called "fluorspar." - "Geology.com"

NEGOTIATING THAT NEW CONTRACT…!!

Are you a mining contractor in the process of negotiating your new contract with the mine, or renewing your contract? Are you 100% confident that your Excel calculations are correct in determining fleet numbers for the contract? What if the distances are beyond what was assumed, will you have enough equipment to sustain the client’s demand? Are your roads accurately set-up in terms of stop signs, single carriage areas, steep gradients, single-bay dumps? What if your equipment availabilities do not materialise as hoped? Do your Excel spreadsheets incorporate these variables? With the HAULSIM simulations you can set up your site accurately to generate realistic results in terms of fleet number

WHAT HAPPENS TO RESOURCE CLASSIFICATION DURING UP-BLOCKING??

When up-blocking a resource model to a mining model it's fairly simple to weight average the qualities and RD's, but what happens to the rock types and confidence indexes (measured, indicated, inferred)... e.g. when one block is banded ironstone, and the other block is shale, what do you call the weighted average of this new block? Same goes for when you have a measured block and add it to an indicated block, you can downgrade according to the SAMREC code so that both blocks are indicated, but what if you have an indicated block and an inferred block, then you can't just downgrade anymore... I normally just keep the original tonnages from the resource model in the up-blocked model, but I wou

MINING ROCKSTAR OF THE WEEK - FELDSPAR!!

“Feldspar” is the name of a large group of rock-forming silicate minerals that make up over 50% of Earth’s crust. They are found in igneous, metamorphic, and sedimentary rocks in all parts of the world. Feldspar minerals have very similar structures, chemical compositions, and physical properties. Common feldspars include orthoclase (KAlSi3O8), albite (NaAlSi3O8), and anorthite (CaAl2Si2O8) - "Geology.com"

WHAT EXACTLY DOES REVENUE FACTOR 1 MEAN?

When I started in mine planning back in the day, everybody was talking about this Revenue Factor 1 thing. At some point I couldn't contain myself anymore, and I asked my manager what does it mean, and he explained: When doing a Whittle Open Pit Optimisation, the software generates an array of Nested Shells, or incremental shells, say in 0.25 intervals. Revenue factor is defined as: (incremental cost)/(incremental revenue). At a RF =1 pit, the incremental cost = incremental revenue, meaning for that increment there is zero profits. So even though the total pit will have PROFIT, as can be seen in the graph below, the next incremental shell will start destroying value because the costs start in

HELP YOUR BOSS - CREATE SCHEDULING OPTIONS!!

Battling with the software to set up a mining schedule? We all know the feeling... when you're losing precious time because of fighting the software instead of running iterations and scenarios... You will never have confidence in your schedule if you do not have 2 or 3 scenarios to test the flex of your system. Your superiors want a number of options, not just one answer. RPMGlobal's XPAC SOLUTIONS products allows you to do just that - run scenarios instead of suffering in silence. With almost a decade of open pit scheduling experience allow me to help you create options for your company, so you can make informed decisions, and understand the risks with confidence!

MINE PLANNING SOFTWARE FRIDAY - TRIMBLE'S TOP-D!!

When I do work for clients, I like to give them options, not just one answer. It's only with options that you fully understand the flex of the system. Same goes for Mine Design. Since 2012, I've been doing all my mine design work using Trimble's TOP-D package. The package allows me to do a best fit to a Whittle shell, honour geotechnical slope angles from a csv file, as well as moving ramps around on the fly. I can even design waste dumps as well. To be honest, I'd be lost without it. Have a look at the clip below, just to see how rapidly it works. Enjoy!!

ARE YOUR MINE DESIGNS SAFE??

How sure are you that your mine designs have the minimum number of switchbacks? Have you tested the impact of having one switchback less, how that reduces your strip ratio and down-the-line costs, not to mention the health & safety of your employees ...? What about your benches & stacks, do they honour the geotechnical slope angles to prevent slope failure...? Your ramp systems on your interim high-walls - do they tie up with your final design and serve as dual access for that rainy day when you need it most...? Difficult questions I know, but prevention is better than cure as they say. Using state-of-the-art mine design software and almost a decade of design experience, I can help you sleep

MINING ROCKSTAR OF THE WEEK - EUCLASE!!

Euclase is a rare beryllium aluminum hydroxide silicate mineral that crystallizes in the monoclinic system. It has a chemical composition of BeAlSiO4(OH). Euclase crystals are usually found in granitic pegmatites and low-temperature hydrothermal deposits. Massive to fibrous euclase is usually found in schists and phyllites. It is safe to say that most geologists have never knowingly encountered euclase in the field. It is a rare mineral, they are not expecting to see it, it is usually present in small quantities, and because most euclase is colorless to white it is easily overlooked - "Geology.com"
